Analog Devices Inc./Maxim Integrated MAX4613CPE

Overview

MAX4613CPE from Maxim Integrated is a quad SPST analog switch with two normally closed (NC) and two normally open (NO) channels, designed for precision signal routing in mixed-voltage systems. It delivers 85Ω max R_DS(ON), 4Ω max on-resistance matching between channels, 9Ω max on-resistance flatness over ±15V signal range, and 10pC max charge injection - enabling high-fidelity sample-and-hold and audio routing in battery-operated and military radio systems.

For engineers reviewing the MAX4613CPE datasheet, MAX4613CPE pinout, MAX4613CPE application, or MAX4613CPE equivalent, key selection criteria include its dual-supply operation (±4.5V to ±20V), rail-to-rail analog signal handling up to ±15V, TTL/CMOS logic compatibility via VL pin, low off-leakage (<5nA at +85°C), and exposed-pad DIP package thermal performance.

Technical Context

The MAX4613CPE implements four independent CMOS transmission gates controlled by separate digital inputs (IN1–IN4), each with matched channel characteristics guaranteed across temperature. Its architecture supports both unipolar (+4.5V to +40V) and bipolar (±4.5V to ±20V) supply configurations, with VL pin allowing flexible logic-level referencing to either V+ (CMOS) or +5V (TTL).

Switching is bidirectional with symmetric R_DS(ON) behavior; turn-on time is <250ns and turn-off time <70ns under ±10V conditions. Internal ESD protection meets 2000V minimum per Method 3015.7, and leakage paths are isolated to V+ or V− - not between switch terminals - ensuring integrity in high-impedance signal chains.

Key Specifications

Pinout & Package

MAX4613CPE uses a 16-pin plastic DIP package (0°C to +70°C operating range) with through-hole mounting and an internal substrate connection to V+. The exposed pad variant is not applicable to this part - only the CPE grade uses standard DIP without EP.

Compared with MAX4613CSE, the MAX4613CPE offers identical analog performance but requires through-hole assembly and has higher thermal resistance; compared with ADG465BRUZ, it supports wider supply ranges and configurable logic thresholds - making it more versatile in mixed-rail military and telecom designs.

FAQ

What is the maximum analog signal voltage range supported by the MAX4613CPE?

The MAX4613CPE supports analog signals from V− to V+ across its full specified supply range. With bipolar ±15V supplies, it handles ±15V signals; with unipolar +12V operation, it supports 0V to +12V. The absolute maximum analog range is limited by the supply rails - never exceeding V+ or falling below V− - and is guaranteed over the entire −40°C to +85°C extended temperature range for the E-grade variants, though the MAX4613CPE itself is rated 0°C to +70°C.

Does the MAX4613CPE require external level-shifting for TTL-compatible logic inputs?

No - the MAX4613CPE includes a dedicated VL pin that accepts +5V directly for TTL-compatible logic thresholds. When VL = +5V, IN1–IN4 recognize VINH ≥ 2.4V and VINL ≤ 0.8V, eliminating the need for external level shifters. This feature is confirmed in the Electrical Characteristics table and Applications Information section of the MAX4613CPE datasheet.

How does the MAX4613CPE manage power sequencing to prevent latch-up or damage?

The MAX4613CPE requires strict power sequencing: V+ must be applied first, followed by VL, then V−, and finally logic inputs. This order prevents internal parasitic structures from turning on. If sequencing cannot be guaranteed, external blocking diodes (as shown in Figure 1 of the MAX4613CPE datasheet) must be added to V+ and V− pins - reducing analog range by 1V but preserving all other specifications including R_DS(ON) and leakage.

Is the MAX4613CPE pinout compatible with the industry-standard DG213 device?

Yes - the MAX4613CPE is explicitly stated in its datasheet Features section as "Pin Compatible with Industry-Standard DG213". Pin functions, numbering, and physical layout in the 16-pin DIP package match exactly, enabling drop-in replacement without PCB modification. This compatibility is verified across all electrical parameters including R_DS(ON), timing, and leakage.

What is the thermal performance limitation of the MAX4613CPE in plastic DIP packaging?

The MAX4613CPE in 16-pin plastic DIP has a maximum continuous power dissipation of 842mW at TA = +70°C, with a derating factor of 10.53mW/°C above that temperature. This value is derived from its thermal resistance (θ_JA ≈ 119°C/W) and reflects real-world convection-limited cooling. For high-current or high-temperature applications, derating must be applied - e.g., at +85°C ambient, max dissipation drops to ~685mW.
